Options and Accessories Installation Remote-Mount Accessory Installation 4-3
4.2.1 Emergency Pushbutton or Footswitch Installation
Mount the switch using the hardware that comes with the kit. Connect the button/switch wires to a
ground pin and the emergency pin, removing the default jumper wire in the rear accessory cable.
The button/switch will short the pins when in-active. When the button/switch is pressed, its contact
opens, the emergency path is un-ungrounded and pulled-high inside the radio transceiver, and
detected by the processor. If an emergency accessory is used at either (or both) J2 connector and
J626 connector, all jumper wires, shorting emergency to ground, must be removed so button/switch
press can be detected.
4.2.2 Horn (External Alarm) Relay Installation
Mount the horn relay in a suitable location (normally under the dash). Connect the relay contacts
across the horn ring switch, typically found in the steering column. Connect the two control wires to a
SW B+ pin and a VIP OUT pin on the VIP connector.
4.2.3 Lights (External Alarm) Relay Installation
Mount the light relay in a suitable location (normally under the dash). Connect the relay contacts
across the head lamp ON/OFF switch. Connect the two control wires to a SW B+ pin and a VIP OUT
pin on the VIP connector.
4.2.4 Gunlock Installation
The O7 or O9 control head can program up to three gunlocks through the programmable buttons.
You can set the time for the momentary trigger using the time-out trigger button. Connect the relay
contacts across the gunlock switch to install the gunlock. Connect the two control wires to a SW B+
pin and a VIP OUT pin on the VIP connector.
It is recommended to install a failsafe/redundant bypass switch for the gunlock. It is suggested to use
a separate timer switch or a manual push-on button switch to activate the gunlock. Connect the
switch from the supply to the gunlock directly, as shown in Figure 4-4. Place the manual button at a
suitable and reachable location, yet not easily seen.
The radio is sold with correct accessory cables and jumpers in order to have
emergency de-activated by default, regardless of the setting in CPS. However, if
cables are not used, or if jumpers are removed without replacing with an emergency
accessory button/switch at one of the accessory ports, the radio will power-up upon
the application of A+. The display may not show an indication that the radio is on, and
this can result in an incorrect operation of the radio as well as excessive current drain
of the vehicle’s battery when the engine is off.
